Dana 60 Length B-body 1971

[road/track]

Hi all,
I need a bit of urgent help, my rear end shop just called and asked me on the total width of my Dana 60.
Currently I'm restoring back to original from being shorted way back in the 80's.
I ordered new drive axles from Cass and they are 29.9" and 31.15" with that my axle housing needs to be flange to flange 57,75" or outside drum - drum 63"
Will this be correct for 1971 B-body?
A lot of copied information and different sources on Internet, if someone have true knowledge I appreciate that.
Thanks

All of your numbers are correct.
